Say that further when diode assembly 17a conducting, flat plane antenna 15 can operate in one first center frequency-band, wherein this first center frequency-band comprises one first low-frequency current path and one first high-frequency current path.This first low-frequency current path comprises two parts basically at least, and first through ground connection connecting piece 151a to the first point of contact 1511, extends to end points 1518 earlier from earth terminal 131 beginnings again; Second portion is also from earth terminal 131 beginnings; Through first electrode 171, diode assembly 17a and second electrode 172; Along feed-in connecting piece 151b to the second point of contact 1512, extend to end points 1518 more again, so the first low-frequency current path is the summation of above-mentioned two parts.And one first high-frequency current path comprises two parts basically at least, and first, passes through to second tie point 1512 through ground connection connecting piece 151a to the first point of contact 1511 earlier from earth terminal 131 beginnings again, extends to end points 1517; Second portion is also from earth terminal 131 beginning, through first electrode 171, the switch 17 and second electrode 172, along feed-in connecting piece 151b to the second point of contact 1512, extends to end points 1517 more again, so the first high-frequency current path is the summation of above-mentioned two parts.Significantly, when diode assembly 17a conducting, flat plane antenna 15 can be reached the operation mode of double frequency.
And when switch 17 not during conducting, flat plane antenna 15 can operate in one second center frequency-band, and wherein this second center frequency-band comprises one second low-frequency current path and one second high-frequency current path.The account form in this second low-frequency current path is only from earth terminal 131 beginnings; Through ground connection connecting piece 151a to the first point of contact 1511; Extend to end points 1518 again, and the account form in this second high-frequency current path is also from earth terminal 131 beginnings, through ground connection connecting piece 151a to the first point of contact 1511; Pass through again to second tie point 1512, extend to end points 1517 again.Likewise, as diode assembly 17a not during conducting, flat plane antenna 15 also can be reached the operation mode of double frequency.In view of the above, but the handheld apparatus 6 of the 6th embodiment is contained the mode of 4 kinds of operational frequency bands altogether.
For example, the handheld apparatus 6 of Fig. 7 the 6th embodiment operates in voltage standing wave ratio (VSWR) sketch map under the different frequency bands.As shown in Figure 7; When switch conduction; The flat plane antenna 15 of handheld apparatus 6 can operate in one first center frequency-band, and this first center frequency-band has a low-frequency current path (can operate in the fundamental frequency f1 of LTE system) and a high-frequency current path (can operate in the frequency multiplication f2 of LTE system).And when switch not during conducting; The flat plane antenna 15 of handheld apparatus 6 can operate in one second center frequency-band, and this second center frequency-band has a low-frequency current path (can operate in the fundamental frequency f3 of cdma system), two high-frequency current paths (can operate in the frequency multiplication f4 and the f5 of cdma system).
Therefore, first and second center frequency-band can have the dual frequency operation of a low frequency (being fundamental frequency (fundamental)) current path and at least one high frequency (being frequency multiplication (harmonic)) current path respectively.Must the expositor, first center frequency-band shown in Figure 7 for example is the LTE frequency band, and second center frequency-band for example is the CDMA850 frequency band, but first and second center frequency-band is not limited thereto.Hence one can see that; The sixth embodiment of the present invention not only can be according to different design requirements and in response to residing environment; Adaptive ground switches on flat plane antenna the center frequency-band of difference; More can in respective frequency bands, have the operator scheme of double frequency at least, so promote the reception effect of flat plane antenna and the convenience of handheld apparatus widely.
Comprehensively above-mentioned, the present invention sees through and a switch is set to change the current path of flat plane antenna.This switch can see through diode assembly and realize, and the conducting that sees through a direct current signal controlling diode assembly whether.In addition; The present invention is formed at a surface of the housing of handheld apparatus with the metal level (being radiant body) of flat plane antenna, and diode assembly, resistance dc component and resistance radio frequency component are arranged on the circuit board, and is electrically connected to the metal level of flat plane antenna via connecting piece; Thus; Can avoid the electronic building brick on the circuit board that the characteristic of flat plane antenna is exerted an influence, and if will with electronic building brick be disposed on the flat plane antenna and be exposed to housing outside, this measure not only will have a strong impact on the global design outward appearance of handheld apparatus; These electronic building bricks more are subject to damage of external force or receive the influence of human body contact, can't be protected and bring into play due usefulness.In view of the above, the flat plane antenna of handheld apparatus of the present invention has that volume is little, operates in the advantage of two center frequency-bands simplicity of design and adaptive.More importantly; More high resilience of design for flat plane antenna; No matter why are the outward appearance of housing and shape, at random therefore one patterned has increased the height of antenna simultaneously on housing; Can improve and improve the reception effect by this, not need to be limited and must be disposed on the handheld apparatus inner circuit board or bearing part by electronic building brick.
Need the expositor, the above embodiments are only in order to disclosing enforcement of the present invention aspect, and explain technical characterictic of the present invention, are not to be used for limiting protection category of the present invention.In addition, any be familiar with this operator can unlabored change or the arrangement of the isotropism scope that all belongs to the present invention and advocated, and rights protection scope of the present invention should be as the criterion with claims.
